LOCTITE® 220

Features and Benefits

Low-viscosity, removable-strength threadlocker for the locking and sealing of small diameter, pre-assembled threaded fasteners under 6 mm (0.234"). Prevents loosening from shock and vibration, but is also easy to disassemble with standard hand tools without heat.
When you have pre-assembled fasteners less than 6.35 mm (1/4") in diameter and need an effective threadlocker that allows for easy disassembly without shearing the screw, choose LOCTITE® 220. This fluorescent, low viscosity threadlocker wicks its away into the thread roots of pre-assembled, small diameter fasteners. Perfect for applications such as adjustment of set screws and small diameter or long engagement length fasteners.
  • For use on pre-assembled fasteners up to 1/4" diameter
  • Prevents loosening and leakage from shock and vibration
  • Can be easily disassembled without shearing the screw
